The heartwarming reason Prince Harry has worn the same bracelet for 20 years

Watching Prince Harry win over the hearts of Australians during the Royal Tour of the Pacific has been extraordinary - just when we thought we couldn't love him more.

The Duke and Duchess of Sussex are only three days into their 16-day visit of Australia, New Zealand, Fiji and Tonga, and have delighted crowds wherever they've gone, including in Sydney and Dubbo. Today, they will tour Melbourne.

Watching Harry brings back memories of his mother, the late Princess Diana, and how easily she connected with others.

It seems fitting that wherever he goes, Prince Harry keeps his mother close to him wearing a bracelet he acquired shortly after her death. The bracelet came into his possession during a trip to Africa, when Prince Charles whisked Harry and his brother Prince William away to help them try and recover from the loss.

The distinctive piece of jewellery has been spotted on Harry's wrist throughout the Royal Tour.

The 34-year-old has also worn it during school exams, trips around the world, at the polo, and it was spotted on his wrist when he first began dating Meghan Markle. He even wore it on his wedding day on May 19 this year.

As for the black ring he wears on his right hand, PEOPLE reveals it is an 'Oura Ring' -- a sleep and activity tracker that identifies stages of sleep and connects to an app on your smart phone to share data.

That could come in handy for Prince Harry just in case there's any lingering jet lag.

Prince Harry has spoken about his struggles following his mother's death, first opening up on a podcast called Mad World, saying initially he shut down but then learned to open up to his brother and loved ones before turning to therapy.

"I have probably been very close to a complete breakdown on numerous occasions when all sorts of grief and sort of lies and misconceptions and everything are coming to you from every angle," he said on the podcast.

He then spoke of seeking professional help from a therapist saying, "I’ve done that a couple of times, more than a couple of times, but it’s great."

"Look, you really need to deal with this. It is not normal to think that nothing has affected you...The experience I have had is that once you start talking about it, you realise that actually you’re part of quite a big club."
